TOBACCO-PRESS.

Specification of Letters Patent. v Patented FebbY 26, 1918.

Application filed August 7, 1917. Serial No. 184,868.

To all whom it may concern:

Be it known that I, ALBERT HARTWIG, a citizen of the United States, and resident of Deerfield, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Tobacco-Presses; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention refers to new and useful improvements in baling presses, particularly that type which are adapted for use in forming tobacco into bundles or bales.

Heretofore it has been customary to bale tobacco and similar classes of goods by using an arrangement in the nature of a screw jack for forcing the pressing head in a direction to compress the material between it and a stationary member, usually the bottom of a container. When said screw is operated by hand, it is obvious that the compression of the material will be by slow and tedious stages.

It is therefore, primarily the object of the present invention to procure an arrangement whereby tobacco and like material may be quickly compressed into bundles of the desired size and shape. This is carried out specifically by means of a lever actuated pressing head.

In connection with the main object of the invention it is, also, an object to provide a simple arrangement of links and levers for effectively transmitting the force of the main or hand lever to the pressing head. e

With the foregoing and other objects in view the invention resides in the novel features of construction, combination and ar- A vrangement of parts, which will be hereinafter more particularly described and claimed, and shown in the drawing wherein the figure represents a vertical, longitudinal, sectional view through a baling press constructed in accordance with my invention.

Referring more specifically to the figure of the accompanying drawing, it will be seen that the compression of the material is carried out in a rectangular body 1 of suitable size, which is positioned'a required dis? elongated rectangular shape is the most desirable, the size of the same, of course, depending upon the amount of material to be pressed, but bales packed in a press approximately four feet'long, by one foot wide, and one foot high are most convenient to handle.

The actual compression of the tobacco leaves or other material designated by the letter T is performed between the relatively thick bottom 4 of the body and the pressing` head 5 loosely mounted and movable in the body, the top of which is open to readily receive the material and said head. The ends of the bottom 4 adjacent the ends 3 of the body are each provided with an opening 6 through which hooked rods 7 extend from beneath the body for engagement with the head 5. The upper ends of the rods 7 are provided with a series of fingers 8 for engagement with the head 5 when it is various distancesaway from the bottom 4, and the other ends of the rods, namely those which project beneath the bottom 4, are pivotally connected with one arm of the bell cranks 9 which are pivoted at the intersection of their arms as at 10 to the under side of the bottom 4. It is obvious that movement of these bell cranks in one directionwill cause the hooked rods 7 to move downwardly, which, when they are engaged by the yfingers 8 with the head 5, will cause the compression of the material T. i

The other, or outwardly, extending arms of the bell cranks 9 have links 11 pivotally connected therewith, said links also being similarly connected with the opposite ends of an intermediately pivoted lever 12, which is keyed upon the transverse shaft 13 journaled in bearings carried by brackets14, which depend from the bottom 4, these brackets 14 are substantially U-shaped and have the bearings referred to secured to their base portions as clearly shown in the drawing. Inasmuch as the openings 6 in the bottom 4 are midway the side edges of said bottom, the bell cranks will, also, be disposed centrally and longitudinally of the body.

A handle in the form of a lever 15 is, also, keyed to one end of the shaft 13 and is adapted to be moved from the inactive position, shown in full lines in the figure, to the active position indicated by the dot and dash line 16. The large arrow connecting the handle 15 and the line 16 indicates the direction of movement of the former during the compression stroke, while the small arrows extending from the ends of the lever 12 showv the direction of movement of this part under the same conditions.

The working of the invention may be successfully carried out-as follows:

The leaves of tobacco or other material are placed in the body 1 until they assume a suflicient height, whereupon the pressingl head 5 is placed thereon and the hooked rods 7 adjusted until the corresponding lingers thereof engage over the top of said head. The parts are then ready to be actuatedto carry out the compression of the materialvT,it being assumed that the handle 15 is in position as shown. The movement of the handle in the direction of the arrow, as hereinbefore indicated, will cause the rotation of the shaft 13 and the movement of the lever 12 and consequently force the links 11 and bell cranks 9 toward each other to thereby move the hooked rods 7 downwardly. Upon completing the indicated movement of the handle 13 toward the left, the material T will be compressed to a considerable extent, and if further pressure is to be applied thereto to contract it into a smaller space, the handle is returned to its initial position and the hooked rods 7 adjusted to engage the lower fingers thereof with the pressing head A5, as indicated in the drawing, care being taken to prevent eX- pansion of the material when said hooked rods are loosened. Repetition of this movement vof the parts may be continued until the tobacco, or like material, has been compressed asuiicient extent and formed into a Ibundle of desired size, whereupon it is wrapped or tied to prevent its returning to its original bulk. f

I claim 1. In a machine of the class described comprising a body, a pressing head adapted to move in said body, a bell crank carried by the body, an operating lever, a connection between onearm of the bell crank and the lever, and a member pivoted to the other arm of the bell crank adapted for detachable engagement with the pressing head.

2, In a machine of the class described comprising a body, a pressing head adapted to move in said body, a shaft pivoted below said body, a lever fixed on the shaft, a pair of bell cranks disposed one on each side of the shaft and pivoted to the body, a connection between the corresponding arms of said bell cranks and the opposite ends of said lever, a member pivoted to each of the other arms of the bell cranks, said members being adapted for detachable engagement with the pressing head, and means for rotating said shaft.

3. In a machine of the class described comprising a body having an opening in each end of its bottom, a pressin head adapted to move in said body, a sha t pivoted to the bottom of the body mid-way between said openings, a lever ixed on the shaft, a pair of bell cranks disposed one on each side of the shaft and pivoted to the bottom 'of the body, a linked connection joining the corresponding arms of the bell cranks and opposite ends ofl said lever, the other armsk of the bell cranks being adjacent said openings, a pair of rods, one being pivoted to each of the last mentioned arms of the bell cranks and adapted to extend through said openings, a series of hooks formed on the free ends of said rods ,for adjustable detachable engagement withv said pressing head, and an operating handle fixed to the shaft for rotating the same.

In testimony that I claim the foregoing I have hereunto set my hand at Deeriield, in the county of Dane and State of Wisconsin this 31st day of July A. D. 1917.
